In an example, a process of forming a polyurethane material is disclosed. The process includes forming carboxylic acid-terminated aliphatic polyol molecules from an epoxidized plant oil. The process also includes chemically reacting the carboxylic acid-terminated aliphatic polyol molecules with an azide material to form monoisocyanate-functionalized aliphatic polyol molecules. The process further includes polymerizing the monoisocyanate-functionalized aliphatic polyol molecules to form a first polyurethane material.

The present invention relates to compositions which comprise highly branched polyesters, to the use of these highly branched polyesters in cosmetics and dermatology and to substituted highly branched polyesters.

The invention relates to polyureas having a weight-average molecular weight ranging from 5,000 to 70,000 g/mol, the preparation thereof, and the use thereof as rheology control agents. The invention further relates to rheology control agents containing polyureas and to the use thereof. The invention moreover relates to formulations containing polyureas.
